Fatigue data for aluminum alloy 5454 in the annealed condition and in the half-hard and stabilized condition, at a test temperature of 300°F (149°C), are given. These data are developed from load-controlled tests and cover the cyclic life region from about 1 × 105 to 2 × 106. The data supplement previously presented data from strain-controlled tests covering the cyclic life region below 1 × 104 cycles.
